In my opinion you should do a search....I in fact posted something on this not too awful long ago....yes, CAFS is great PROVIDED that you take the time to train with it first...it isn't a slow process to get everything right and EVERY pump operator has to know what they are doing....we find we cut our water usage by almost 80% (rural Department we have to carry our water to the scene) When doing Fire Flow calculations you can divide your results by 4 for what your "new" flow would be if using CAFS....
